Problem

A heat exchanger/boiler in an industrial facility needed to be preserved during a plant shutdown.

Solution

VCI powder was used to preserve the internals and a wet layup process was used where the VCI powder was disolved in water. Being environmentally friendly the wet layup solution can be reaidly disposed of.

A dry layup process could also have been used where VCI powder is fogged in to the boiler/heat exchanger.

Benefits

• Minimal effort in achieveing corrosion protection using wet layup
• Equipment preserved for an extended period of time
• Disposal of the water solution
